Length of diagonal of the rectangle=
√( length) ²+( breadth) ²
=√(20) ²+(12) ²
=√400+144
√544 m
. '. Length of fence= √544 m
Perimeter of the triangle formed by the diagonal of the rectangle =(12+20+√544)
=(32+√544) m

Let

be the root with the positive square root and

the root with the negative square root. Then

The simplest quadratic with these roots can be written as
Answer:
11/16
Step-by-step explanation:
There are 9 red crayons, 2 blue crayons, and 5 yellow crayons. We can represent this as a ratio of 9:2:5. Now we have to combine the red crayons and blue crayons so it's 11 red and blue crayons: 5 yellow crayons OR 11:5. Then we add those two values to find out the number of crayons there are, and there are 16. So out of 16 times, you will pick up a red or blue crayon 11 times. So this fraction is 11/16 which is already its simplest form.
